The best is only getting better. Windows 8 was a great platform, but now Windows 8.1 adds a lot of new features. Windows 8.1 is Faster and more stable on our test system then windows 8. The start button is back, you can boot to desktop, and your wallpaper can be the background of your start menu. The Start menu has been overhauled. You can resize the icon and you push the arrow to see all apps. No more need to right click. We have been running Windows 8.1 for over a month now on all our systems and we love it!
To get the upgrade, make sure to get all Windows 8 updates and turn off your firewall then go to the apps store and download it.
